ResumoPhosphacumulen-Ylide 1 addieren acide Verbindungen 4 zu Phosphoranen 5, die durch intramolekularen Ringschluß (meist Wittig-Reaktion) Heterocyclen 7 liefern. Cumulated Ylides, XIV. Phosphacumulene Ylides – Building Blocks for the Synthesis of Heterocyclic Compounds Phosphacumulene ylides 1 and acidic compounds 4 combine to give phosphoranes 5, which cyclize by an intramolecular reaction (mostly Wittig reaction) with formation of heterocycles 7.
